MOP HEAD.

1 Application filed November 14, 1924. Serial No. 749,814.

T all whom it may concern-g Be it known that I, HERBERT M. SrURoIs, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of ltiissouri, have invented certain new and useful Improvements in Mop Heads; and I do declare tl'lQTOllOWlDg to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make .and use the same, reference being hadto the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to mop headsand the primary object of the invention is to provide an inexpensive easily constructed reversible-mop head whereby the mop fabric may be reversed so that both sides can be used. The device is shown in combination with a mop fabric in theform of an envelope which fits over the head and which may be r'emovably secured thereto in a convenient mannerJ 4 The details of construction illustrating the generic e'mbodimentof my invention will i be specifically described hereinafter, refertion.

encebcing had to the accompanying drawings,-in which'- v I Fig; 1 is a perspective v ew of a mop head constructed in accordance with my inven- Fig. .2 is a detailed perspective view of the ferrule for securing the handle-of the mop tothe shank of thelheadr Fig. 3 a sectional View through the shank and the ferrule in cooperative relation. a c

Fig.4 is a detailed perspective view of one of the shank elements, and

Fig. is a perspective view of the completed mop, part of the handle being broken away.

The mop head is shown as comprising a substantially pentagonal flat member or frame made of one piece of wire. The single strand of wire is bent midway its ends at 1 to form two diverging end bars or arms 2 and 8 terminating in longitudinally disposed parallel side bars 4 and 5 bent transverselyto form end bars or arms 6 and 7 then bent to form diverging inwardly turned arms 8 and 9 with a space 10 between them and between the arms 6 and 7,so that the shank to be hereinafter described may swing in an unobstructed manner. The diverging longitudinal arms 8 and 9 are bent at their. inner ends to form transverse members 11 and 12 terminating at the longitudinal center :of theframe, the members 8 and 9 being then bent back upon themselves to form braces 13 and 14 which may be spot welded at 15 and'16 to the arms 4 and 5, thus a substantially pentagonal skeleton frame is provided to be received by the mop fabric.

The members 12, 13 and 14 combine to constitute brackets to receivea sheet metal clip, 17 formed by bending a piece of sheet metal over upon itselfand crimping it at the end edges of the sheet as indicated at 18,

the intermediate portion of the sheet being formed witha tubular portion or bearing 19 to receive the outstanding ends 20 and21 of a wire shank which is bent intermediate its ends to form aloop 22, the shank intermediate portions 23 and 24 lying close together with the ends 20 and-21in the bearing 19 So' that the shank is hinged to the clip within the perimeter of the'frame.

There is a cap piece 25 fitted over the loop and having a shoulder 26 at the intersection of the convex end 27 and the enlarged threaded portion 28, the shank being provided with an opening 29, the purpose of which will be presently explained. The lower edgeof the cap piece is bent under to form a groove 30 to receivethe upper edge 31 of a cone 32 having a lower restricted end fitting around the members 23 and 24; The ferrule is shown consisting. of two pieces. The sleeve 33 has prongs 34 imbedded in the handle 35. The opposite-end of the member 33 is provided with a shoulder 36 with an edge bent under as at 37 to receive the inturned flange 38 of the member39 of the,

ferrule.

The member 39 is provided with a collar 40 to act as a stop for the threaded collar or ring nut 41 which has an inturned flange 42. The threaded portion 43 of the collar 41 engages the threaded member 28. The ferrule member 39 has prongs 44 which are adapted to engage the openings 29 when the handle is applied. In this manner the prongs 44 can be easily inserted in the openings 29 and since the collar 41 has free play on the ferrule member 39, it will be ap parent that the collar can be quickly screwed on the threaded member 28 to make a quick tight connection and liability of the collar unscrewing will be eliminated because there can be no relative turning movement of either "the ferrule or the shank head to loosen the ring nut 41, therefore the projection-44 and the openings 29 constitute a nut lock. By providing a nut lock, the threads on the collar ll and the threads 28 can be made relatively coarse so quick adjustment can be made. If there was no provision :rnade for locking the parts, a finer thread would be necessary and even then there would be no assurance that the parts would become accidentally detached.

lhe pentagonal frame is 're'ceive'cl in an envelope 45 which constitdtesthc mop fabric, there wbeing'an opening 46 through which the frame may be inserted and the mop fabric can be securely fastened to the frame by the two sets 47 and 48 *ofst'ring or tapes which may be wound around the cleats 49 and '50 on the bars 8 and 9 (see Fig. 1). Since theen-velope entirely covers the frame and since the shank and f-rame are hinged together, it 'will b'e apparent that the "mop is entirely reversible.

l-am aware that a reversible mop or brush has been used prior to any invention as for example, the mop disclosed in the patent to W. Glass, December 15, 19'14:,#1-,12-1,0O8 and that wire frani'es -for mop heads have also been used prior to my invention. A wire frain'e is=shown in the patentto Too'f, patented October 15, 1918, so I do not claim broadly the wire frame nor "the reversible mop fabric, but any invention consists rather in *the novel manner form ng a rigld frame of a -single piece of wire in the form of "a flat broad head so'th'at the fabric can have a flatb'earing' 'surfaceon when it-opera'tes anda byno m'eans unimportant part of myinvention is the novel manner of forming the frame and the manner -of securing the shank thereto.

.The ferrule for 'connectinfgthe head to the "handle'or mop stick constitutes the subject wire bent intermediate its ends to provide diverging portions. parallel arms integral with the diverging portions, inwardly extending portions at the ends of the parallel arms, inwardly directed diverging arms at the inner ends of the inwardly extending portions and terminating in reversely bent ends to provide clip brackets, the brackets being fast to the parallel arms, a sheet metal clip fastened to the -brackets and a shank hinged to the clip.

2. A floor-polishing mop head comprising a flat frame formed of wire bent intermediate its ends to provide side bars and end bars, one set of end bars being spaced apart, the spaced ends being bent inwardly to provide'div'erging arms within the perimeter of the 'frame, the ends of the arms being bent laterally one toward the other and terminating at the longitudinal center of the frame in reversed bends, doubled upon the lateral portions to provide bracket members, the ends of the wire being secured to the side bars, all parts of the frame being in the same "plane, a shank and means for hinging the shank to the bracket members.

A floor polishing mop head comprising 'a flat frame "formed of wire having midway fvers'ed bends at substantially the longitudinal center of the frame so that the end ;portions of the wire are doubled back upon the transverse portions, ;the ends of the wire being fastened to the parallel portions, and means for fastening a mop handle to the transverse portions.

In testimony whereof I afiix my signature.

HERBERT M. STURGIS.
